FIELD OF THE INVENTION

The present invention relates to substituted isoquinoline amidecompounds and substituted benzamide compounds that affect the functionof kinases and the function of transporters in a cell and that areuseful as therapeutic agents or in conjunction with therapeutic agents.In particular, these compounds are useful in the treatment of diseasesand disorders of the eye, such as glaucoma, of the respiratory system,of the cardiovascular system, and for diseases characterized by abnormalgrowth, such as cancers.

BACKGROUND

A wide variety of hormones, neurotransmitters, and other biologicallyactive substances control, regulate, or adjust the functions of the bodyvia interaction with specific cellular receptors. Many of thesereceptors mediate the transmission of intracellular signals byactivating guanine nucleotide-binding proteins (G proteins) to which thereceptor is coupled. Such receptors are generically referred to asG-protein coupled receptors (GPCRs) and include, among others,adrenergic receptors, opioid receptors, cannabinoid receptors, andprostaglandin receptors. The biological effects of activating thesereceptors are not direct but are mediated by a host of intracellularproteins. The importance of these secondary proteins has only recentlybeen recognized and investigated as intervention points in diseasestates. One of the most important classes of downstream effectors is the“kinase” class.

Various kinases play important roles in the regulation of manyphysiological functions. For example, kinases have been implicated innumerous disease states including, but not limited to, cardiac disorderssuch as angina pectoris, essential hypertension, myocardial infarction,supraventricular and ventricular arrhythmias, congestive heart failure,and atherosclerosis, respiratory disorders such as asthma, chronicbronchitis, bronchospasm, emphysema, airway obstruction, rhinitis, andseasonal allergies, inflammation, rheumatoid arthritis, renal failure,and diabetes. Other conditions include chronic inflammatory boweldisease, glaucoma, hypergastrinemia, gastrointestinal indications suchas acid/peptic disorder, erosive esophagitis, gastrointestinalhypersecretion, mastocytosis, gastrointestinal reflux, peptic ulcer,pain, obesity, bulimia nervosa, depression, obsessive-compulsivedisorder, organ malformations (e.g., cardiac malformations),neurodegenerative diseases such as Parkinson's Disease and Alzheimer'sDisease, multiple sclerosis, Epstein-Barr infection, and cancer (NatureReviews Drug Discovery 2002, 1: 493-502). In other disease states, therole of kinases is only now becoming clear.

The success of the tyrosine-kinase inhibitor ST1571 (Gleevec) in thetreatment of chronic myelogenous leukemia (Nature Reviews Drug Discovery2003, 2: 296-313) has spurred considerable efforts to develop otherkinase inhibitors for the treatment of a wide range of other cancers(Nature Reviews Cancer 2003, 3: 650-665). Seven additional kinaseinhibitor drugs have since been brought to market, establishing kinaseinhibitors as an important new drug class. Currently more than 100protein kinase inhibitors are in clinical development (Kinase InhibitorDrugs 2009, Wiley Press).

In view of the role that kinases have in many disease states, there isan urgent and continuing need for small molecule ligands that inhibit ormodulate the activity of kinases. Without wishing to be bound by theory,it is thought that modulation of the activity of kinases, including rhokinase (ROCK), by the compounds of the present invention is, in part,responsible for their beneficial effects.

An additional area of fruitful research in medicine is the study ofmonoamine transporters and the benefits of inhibition thereof. Monoaminetransporters (MAT) are structures in cell membranes that transportmonoamine-containing neurotransmitters into or out of cells. There areseveral distinct monoamine transporters, or MATs: the dopaminetransporter (DAT), the norepinephrine transporter (NET), and theserotonin transporter (SERT). DAT, NET, and SERT arestructurally-related, and each contains a structure of 12 trans-membranehelices. Modern antidepressants are thought to work by enhancingserotonergic, noradrenergic, or dopaminergic neurotransmission bybinding to their respective transporter, and thereby inhibitingneurotransmitter reuptake and effectively raising the concentration ofthe neurotransmitter in synapses. Examples of drugs that are thought tooperate by this mechanism include fluoxetine, a selective SERTinhibitor; reboxetine, a norepinephrine (NET) inhibitor; and bupropion,which inhibits both the NET and DAT (He, R. et al. J. Med. Chem. 2005,48: 7970-9; Blough, B. E. et al. J. Med. Chem. 2002, 45: 4029-37;Blough, B. E., et al. J. Med. Chem. 1996, 39: 4027-35; Torres, G. E., etal. Nat. Rev. Neurosci. 2003, 4: 13-25).

Glaucoma causes deterioration of the eye's optic nerve, the nervebundles that carry images from the ganglion cells of the eye to thebrain. Increased IOP is a hallmark of the most common forms of glaucoma,and this increased intraocular pressure likely damages the optic nerveand ganglion cells through multiple mechanisms. Current glaucomamedications act by reducing intraocular pressure, either by slowing theflow of aqueous humor into the eye or by improving the drainage of thisfluid from the eye. Inhibitors of rho kinase have been shown to reduceIOP in rabbits and monkeys by increasing aqueous humor drainage throughthe trabecular meshwork (Tian and Kaufman, Arch Ophthalmol 2004, 122:1171-1178; Tokushige et al., IOVS 2007, 48(7): 3216-3222). Several linesof experimental evidence indicate that modulating the activity of rhokinase within the aqueous humor outflow pathway could be beneficial forthe treatment of patients with glaucoma (Honjo et al., IOVS 2001; 42:137-144; Waki et al., Curr Eye Res 2001; 22: 470-474; Rao et al., IOVS2001; 42: 1029-1037). Considerable evidence suggests that thesympathetic nervous system plays a significant but complex role in theregulation of IOP (Nathanson, Proc. Natl. Acad. Sci. USA 1980;77(12):7420-7424). Sympathetic nerve fibers innervate the ciliaryprocess and trabecular meshwork (Ehinger, Acta Univ. Lund Sect 2 1964;20:3-23; Sears, 1975, Handbook of Physiology, Endocrinology VI. EdsAstwood E & Greep R: 553-590) and both sympathetic stimulation andlocally applied β-adrenergic agonists such as epinephrine decrease IOP(Sears, 1975, ibid; Dayson et al., J. Physiol. (London) 1951;113:389-397).
